1. They photosynthesize and produce flowers – and that’s about where the similarities between Bladderworts and plants, in general, end

2. This gas absorbs visible light so well that plants could not photosynthesize even if they somehow retained their leaves.

3. Algae are all able to photosynthesize, that is, they use energy from the sun (photosynthesis) to make sugars inside the cell.

4. The mechanism of this falling yield was not clear, but might involve increased respiration during warm nights, which expends energy without being able to photosynthesize.
